Hello, I'm trying to get started using Orange for some analytics project of mine. I've downloaded it to my Mac, mounted the volume, and dragged the Orange.app bundle to my Applications folder. I double click it, OS X asks me the security question about running an app downloaded from the Internet to which I respond 'Ok', and then... nothing. Nothing starts.

I've searched the forum and Googled for this, without much success. Only question was from a few years ago, they suggested checking the console output. This is what may be related:

Ok. So the problem was that both matplotlib and scipy are importing PIL but in a different way causing the PIL._imaging C extension being initialized twice and this crashed (although the latest versions of both libraries use the from 'PIL import ...' convention).
